Abstract
This study was a retrospective descriptive study. The objectives were to determine the costs and formulate the cost function due to HIV and AIDS treatment from a provider perspective for the fiscal year 2018 at Phra Thong Kham Chaloem Phrakiat Hospital, Nakhon Ratchasima province. Descriptive statistics were used to summarize demographic characteristics and costs. Stepwise multiple regression was employed to construct the cost function. Ninety-six patients with complete cost data were analyzed. Male and female was equal. More than sixty-nine percent aged higher than 40 years old (mean age 42 years). The total treatment cost was 1,652,314 baht, or an annual average of 17,212 baht per person. Based on the fitted regression model, the significant explanatory variables included drug resistance, the number of out-patient visits, age, and adherence to treatment. The model could explain fifty-seven percent of the cost (Sig. F<0.001). In conclusion, the present study provided a description of costs of HIV and AIDS treatment. It also explored factors affecting institutional costs. These data can assist financial and efficiency management.
